Prosecutors say a Colorado man accused of killing 10 people at a Boulder supermarket in 2021 is competent for trial. The prosecutors said Wednesday that experts have determined that a man charged with killing 10 people at a Colorado supermarket in 2021 is mentally competent to proceed toward a trial. The district attorney’s office announced Wednesday that experts at the state mental hospital say Ahmad Al Aliwi Alissa no longer has a mental disability that prevents him for helping in his defense and can proceed with criminal proceedings. A judge still must accept their conclusion in order for proceedings to resume, it said.
